Acarus Siro Mite IgE Test in Idaho

What this test measures

Storage mites are tiny organisms that thrive in humid grain, hay, straw, and packaged foods such as flour. Acarus siro is one of the more common species, and its allergens can become airborne when stored materials are disturbed. People who work with agricultural products or live in damp housing may notice nasal congestion, sneezing, itchy eyes, or asthma-like symptoms around these exposures.

The test measures allergen-specific IgE in serum using a quantitative immunoassay. A single blood draw is enough, and the laboratory reports the level of Acarus siro-specific IgE along with a reactivity class. Because storage mites share allergens with house dust mites, results are usually reviewed together with other mite and mold tests to build a complete picture.

This test is not a diagnosis on its own. Sensitization means the immune system recognizes the allergen, but symptoms depend on exposure and individual sensitivity. Clinicians use the result alongside a symptom history, physical examination, and sometimes additional testing to decide whether avoidance measures or further evaluation are appropriate.
